'.lhe object of my .invention is a machine known as a bundlea that `is .to say enabling parcels and packages to be made up with a varying number of parts, such as boxes for instance, that are parallelepipedic in shape as a rule, said parts being arranged against each otherY in one or several layers, and the collected parts being enclosed in a sheet of paper wound round them and .closed by folds that may be stuck.

Qne o f the features of this machine Vlies in the fact that the parts, -collected together according to the number required and constituting when put together a p arallelepiped assuming the actual shape desired for the package, are moved with a horizontal motion towards a sheet of paper arranged vertically and suitably stretchedg'this paper sheet is thus folded into Ueshape round the front surface of ,the package and is engaged at the same time as .the latter .during its subsequent motion .inside a dieor mould inside which Aare formed the nal Vfolds .of the paper While the same way lfor .any unerennesses in length of the packages.

The iront folds of the paper strip are shaped through the action :of the two tables of the .die against the progress .of the package and the rear folds .are .shaped by .hinged shoes uor blocks bearing on the rear surface of the package. Some of these blocks are used at the same time to lensure the .continuation of the travel of the package in the mould when the first -pusher member has played its part in admitting the package.

Finally the edge plates are provided with oblique sloping surfaces in which are engaged and are guided the side vfolds of the paper for the folding over `of these vfolds against the end sure faces of the package.

The following disclosure referring'to the ac! companying .drawings given 4as a .nonfrestrietive example will allow a clearer understanding to be .formed `as to how the .invention may be .carried 01.112 while the particular features that make their appearance both in the drawings and thedescripf tive matter, naturally, form part of the invention- In `said drawings:

Figure .32 illustrates the arrangement ensuring the intermittent feed of `certain of the machine parts.

In the machine, the package assumesV a horizontal movement in the direction of the arrow' F so as to enter in succession `the positions illustrated in Figures 1 to S. In Figure '1; the front lfold of the paper strip I has been shaped along the edges cdcd and the side front folds alongV the edges dd' and cc'.

In Figure 2, the rear upper fold has been'inade' along the edge a'b'.

In Figure 3, the second rear fold likewise has been shaped along the edge ab, this second fold being stuck to the first by means of paste spread beforehand on the portion 2 illustrated by hatchings. In Figure 4, thev rear side folds have been shaped along the edges ca bb; In'Figure 5, the upper end tongues Yhave been folded over round the edges ad, bfc'. Vlfastlycin Figure 6 the lower end tongues have been folded in their turn'along the edges ad, be and pasted to vthe previous Itongues by means of paste spread beforehand'on the portion 3 illustrated also `by hatchings.. "f'lhe ymachine is suppliedin a continuous .way b'yfany vmeans, such as an. endless lbelt of which the 'endrnay be'seen at 'i in Figure?, that brings singly the component parts or boxes that have toformthe successive packages lon. to a table 5 at the end of which is placed an elevator tray B equal in length to that of the longitudinal "edges ab, ab' of the package; as a matter of fact the tray 'S lies to the right of its position as shown in Figure 7 so that the supporting rod 'i actually assumes the position 'I'ashown in dot and dash lines. An 'attendant or intermittent mechanism, not shown, such as for instance a turning arm, shifts on to the elevator tray 6 the boxes .placed on the table 5. At the end of the elevator tray 8 is a pedal 8 pivoting round the spindle 9 and constituting a detector. When the tray`6 is full, the.endboxorcomponentpart bears on the pedal 8 r and thelatter through automatic gearing or an electric time-switch'for instance, causes the starting up of the machine for the cycle of making-up'for the package of which the component parts nowflll the tray This tray is then raised and moves Afrom the position Ea shown in Figure ll to the position 6b in front of the die.

In this upper position, the tray Eb is in front of a pusher plate Il carried by a frame Il that may slide on two xe guides 2, I3, the actual framebesides being furnished with two clamping plates It', l5 that are vcarried by hinged levers i6, il and may be clamped against the end surfaces of the package to prevent the latter from falling. When the plates le, i5 thus clamp the packagethe elevator E drops again to take up its originalposition Se in alignment with the table E, the package being held through pressure be tween the clamping plates I, I5 of the pusher. The latter then begins its travel in the direction of the' arrowF and finds at once in front of it thepaper-sheet l. The latter is held vertically onfeach side of the' package between smooth rollers I8 that are suitably controlled and that have ensured the positioning of the paper, and rubber-'coated rollers le that are idle presser rollers.

At this stage of the circuit, the rollers I8 are stopped and unable to turn; they set up consequently a certain resistance to the sliding of the sheet and ensure as a result its tension when the package moved forward by the push-rod is fed to it and urges it forwardly;

The rubber-coated rollers i9 are then driven into rotation by the movement of the sheet. The pusher carries on its movement in the direction F; the sheet is first of all bent as may be seen in Figure 1l, on which the pusher member has come fromA I@ to Isa. The front folds round the longitudinal edges ed, cd are started through lthis movement. The package and the paper sheet then enter the die or mould, whereby the 'folds cd and c'd are ended oil.

The control of the clamping plates I i: and I5 is carried out so as to ensure their spacing apart and then their bringingtogether in order to take and clampthe packageand to hold it during its transportation while theirdrawing apart releases the package when the'latter has been introduced intothemould.

Forthis purpose, the leversA I 'and I 'carry'ing' the plates Hand I5 respectively extend atV 58a and Ila.' beyond their pivoting point-(Fig. 26) and these extensions are connected togetherby rods H36 to a' rocking-lever vIEBI vpivoting at 92 and subjected tothe action of areturn spring IUS. This spring tends to place'this rockinglever in the position shown in Figure" 26,'for which thej plates I4 and I5 are Vbrought vcloser to' each other, which ensures that the package is kept com ined between them.

On the frame II, carrying the pusherl, 'is setto pivot a lever |04 subjected to the action of a spring |05. V

At the time o f the forward movement of the frame II in the direction 'of the arrow F and towards Vthe end of travel of this frame, that is to sayY when the package isinsertedlin the die or mould, the lever Itis comes up Aagainst Yaffixed stop. |166, The lever Ild then pivotsV against the action ofthe spring I'tFig. 27) and acts on the extensionY Ilia of the lever I6 thus causingthe angular movement of this lever and consequently of the lever {7;} The plates I4 and I5 are thus drawn apart-from eachother and :the package is released. The frame-'I'I'then st arts its withdrawing movement as illustrated by arrow Fi (Figure 27) so as to pick up another'package; the lever |04 isthen'no longe;` in contactwith the stop IGS, but'the rplates I@ and I5 however are kept apart from each other, since the lever H34 remains propped obliquely against the tail end lea of the lever I6.

When the frame II reaches the end of its rear travel, that is to say when afresh package has been engaged by the tray 6 between the plates I4 and I5, the tail end I 6o strikes against a fixed stop IQ'I (Fig. 27) finished off by a slopingsurface, that causes the pivotingof the lever IE. The plates I4 and YI5 draw thus apart a little more from each other in orderto take the fresh package. The lever IM thus bears` no longer against the extension Ia and under lthe action of its return spring, returns to its inoperative position. 'The plates je and I5 are nally drawn near each other by the spring I G3 inorderV to clamp the fresh package as'rsoon as theframe II starts ,up again its forward movementin the directions'. i

The mould is providedwith a lower horizontal table 20 and an upper Vhorizontal tableZIthe height of which above the first one is substantially -edualtothe heightlof.' the package, the ltabley 2 Il being' however capable o'f yielding verticall-y so asv to make-up .for any lack of uniformity inlthe height 4of the packages. Thef setting of this'upper table 2| is'illustr'ated in Figures 23 and 24; It is hinged to the ends of four bent levers, arrangedsymmetrically ini pairs, Ypivoting round xed ares. 23 and connected together at their free'ends by rods 251l Thelatter constitute with the tablezi' parallel motions so that the actual table 'always keeps' parallel to its original position. A-"counterweight 24-5 may be added to lessen' the action of. the weight of the table 2|. Lastly,` the inoperative position of the table corresponding tolthe"pac'kage least in height .is defined by a screw stops26. On their.. front edge the tables 20. 2| .show sloping flaring planes 2|la,`2|a which planes produceva widening out entrance simplifyihg the insertion of the package into the mould. I l'Since thepackage is pushed forward at the same :time zas the paper sheet the folds are shaped round the edges cd and cld'. In additionwhen the package has performed a portion of its travel between the tables 20, 2|, it reaches two shoes or blocks 2l', 28 arranged vertically on each side ofthe package and that fold back the paper round the edges cc', dd' (Figure 10) so that the making up stage illustrated in Figure 1 isreached. Each of these shoes 21, 28 is made up of two portions, one 29 at a xed level, the

other 38 capable of a Vertical shifting. YEach of the portions 29 is fastened to the end of one of the two edge. plates 3|, 32 ofthe mould. The other portion 33 .ishingedf on the corresponding edge plate 3|', 32 'by means of two small rods 33 constituting a parallel motion. A spring 3.4 tends 1 to move the portion .30 upwards to press it against the upper table2 A stop 30a restricts thepossible shiftingof the portion 33:50 thatthere repaper- .andits' foldingyalong the edges cc,;dd1.

The edge plates 3|, 32-may yield horizontally, .in accordance with the differences in length of the packages. -Each of them is set'for this purpose on two-small rods 35 pivoting .round vertical axes 36 carriedby the lower table (FiguielO). These small rods 35 constituting parallel motions ensuretheparallelism between the plates-3| and 32 and the direction of forward feed of .the package. 1 vSprings 31 tend to keep between thesejedge plates a space equal to the minimum lengthv of aipackage, the inoperative position being deiined byscrew stops 38. So far the manner, in which thev foldingstage of Figure 1 has been arrived at, has been disclosed. The parts thaten-sure the fashioning of the subsequent folds will now; receive attention. K

-Tothe upper table 2| are hinged. around axes .3Q-,two -benjt leversgqlll arranged symmetrically and..ca rrying a shoe 4| by mean-s -of-a small-,nod dziliigure 11); When=the package arrives at the position shown in Figure 12, the shoe 4| passes vtlircaughfa transverseslotll offrthe upper table 2| :andpmes to bear on the rearsurface of the vv*package while shapingthe upper rear fold around'lthe edge afb'fFigure 2) l f The lworkingof the shoe 4| will nowbe-given with .reference to AFigure 29,

One-of the levers 40 mentioned abova, is fin-- ished off at the end opposedto the shoe 4| by an extension ending with'a blade H0. Throughengagement with the port ||I of. the-11ppertable 2|, this blade may form avprojectionfinside the mouldias shown in dot and dashlines-at |Hla; In this position, the lever 40 is brought into posi-i tion Mia under When the package is moved in the mould between the tables 20 and 2|, itproduoes during its forward travel, a thrust on thel blade- ||0 that thus moves from the position shown in-bro-` ken Ylines to that shown in solid lines;"Ifhis.`

angular movement ofthe blade involves the pivoting of the lever 40. The shoe 4| is therefore applied on the package and this is brought'about by means of the spring H3 inserted between the arm k| I4 rigid with `the lever 40 and thetail end of the lever 42. v f A1 As soon as the rear upper edge of vthe'package has come sufficiently to the front of the shoe .41; the latter pivots around its hinge axis atthe end ofthe lever 42 and while retaining its pressure .on the package enters the vertical position shown Vin Figure 13, the result of which isa perfect folding of the paper sheet. i

As soon as the package, asa consequence of Lits forward movement inthe direction of the arrow F, has`r released the blade H0, thev latterwill return, under the` action of .thefreturn'spring H2, intothe position shown at |011 in* Figure 29; The 4assembly thus disclosed may vbe finished off by .a locking mechanismintended to keep'the shoe 4| substantially in the position shown. in Figure 29, duringV the withdrawal lof thepusher Hl, and to release it when the latter has cometo the lendof its .rearitraveL Y For this purpose, the assembly disclosed above is linishedoff by `a. lever H5 .showing a .recess in which is engaged the endr H3 .of .the lever 4|). This lever lisoonnected byv a linkage `.|.l'|, MB including the bellcrank,.| i9 with` a lever 123 .that may be moved angularly through'` the actiony of a stop,A |2i .rigid with the pusherV In. i

.When this stop .meetsthe ,lever .1 .|20 :towards the end of the .return travel of the pusherlll, the lever H5 is vdrawn back andlees' .leverMl that'isthen brought vback into 'theposition 40a shown in dot and dash lines infFigureZH.' When, at the i ,loeginningA of 4the operations.; the pedal 8 .has been actuated by thapartszarranged on Ythe elevator tray 5. and has :begun the operae tive cycle voi the machine, .a gearing has started rotating the `nlaiii-s'haft 50 rarrying a -numbe'r 'of the latten the cam 5|;v causesthe' pivoting of a lever 52 around afixe'd hingeconneotion 52a: This lever 52 draws, through a hingedA lever '53, aA pinion 54 running on .a fixed rack- 55. The pinion 54 engages with a rack '516 :fastened on-.a carriage y58 moving on :two'parallel guidesa; Sincethe rack 5'5 is stationary as has been stated,

l the translational movement ofthe carriagetheree shown in Figurev `12, thatis toxsay just before :the

sliding of the carriage 58,t'he shoe. 6| v,is moved angularly around its hinge axis on the smallP nod and ,moves Atlfius.fror1;1 the position'illusliafted the .aotion'of the return spring in'Figure lfltothat v'shown in Figure 12. This rotary 'movement ofthe shoe starts 'the lower fold around the edge ab. Lastly,the shoe Si is completelyrai'sed-and is thus brought to press against the rear'szurfaceof the package while-perfecting the lower rear Lfold and the pastingof thisfold bythe paste spread on at 2|, which corresponds to the folding stage illustrated in Figure 3.

In Figures 11 and 12, the various control parts for the shoe |"have been shown diagrammatically; Y yReferring to Figure 30, it will be seen that each ofthe rods 59 mentioned' above is provided with a. roller |25 kept pressed against a sloping surface |28, through the action of a spring |21. Thefsloping surface I|26 .is hinged at the end of a fixed roller-track '|28 andis supported by a cam 29.v connected by 4a suitable linkage to a lever-133.`y-` This lever |39 isA 'controlled by'a cam I3| keyed on the main shaft 53 of the .machine Theangular movement of the cam |29 causes the-lifting of the sloping surface |23 and consequently the verticalY movement of the shoe 6i that impinges'against the package and passes from-the position shown inl-Figure l1 to that shownin Figures 12 and 30 to complete the lower rear fold as has been explained.`

.When the carriage 38 begins to move, the roller |25zby rolling on the sloping surface |25 then on the roller-track |28 keeps the shoe in its raised position, which enables the latter to ensure the drawing. of .the package duringthe remainder of the travelof the package through the mould. -'The shoes 62 and33, that, upv to'now, were'in their inoperative position shown in dotted lines iniFigure 10, then come into action; f These shoes .92 and 33 are each carried by rod 64 pivoting on a rod 55 iixed rigidly With a driving spindle '63. "I'Ihe spindles 63 are driven in rotation and consequently the shoes 32 and 63 are pressed against the rearsurface of the package. .The point atl which'the shoes are pressed on'the'package is 'odset in relation to their hinging` on the small rods 34;.so that. these shoes, when they are'y pressed on the package, pivot round thevedges'aa',V 13b-1.0i the latter by moving fromthe position shown in Figures and 14 to that denoted by lFigures 17 and' 18.V In this pivoting movement,'lthe shoes 62 and 63 fold back the paper sheetround the edges aa' and bb thus formingithei'rear side folds (Figure 4). .sin actual fact, leach of the shoes B2 and 53 is double and is. formed by two superimposed parts such :as 62a and 32h (Figures 15, 16 and 31). :.The'lower part of each of the shoes (part 62a for shoe 62) is set so as to leave between it and the .lower table 20 aV slight play :i allowing the passingof the lower end tongue that the paper showsat the .folding stage ofv Figure 4.

The upperrpart 62o is set on the spindle 66 so that it mayaccompany the upper table 2| in its possible. vertical movements while preserving between the upper edge ofthe part 62D and the table the play y' necessary for allowing the passage of the upper end tongue piece. 1

For this purpose, the rod 65o controlling the part 62h of' theshoe (Figure 16) is fixed rigidiy withfa sleevel that may slide without turning on the spindle G6. This sleeve is subjected A with a bevel pinion |35 engaging with a toothed segment |36. This segment may pivot at |31 and is furnished with an extension |38 on which bears and may roll a roller |39 carried by a lever |60. The two levers |23 are keyed on a common spindle that may be moved angularly by the action of a vearn |42 keyed on the control shaft 50 of the machine. This cam acts on the lever |133 connected by the rod |44 to a lever |45 keyed to the shaft IM. Under these conditions, it will be readily understood that the cam |42 causes during its rotation the pivoting of the shoes 62, 63.

yThe package, pushed by the shoe 6I. driven itself, as described already, by the slide 58, engages between the edge plates 3| and 32 (Figures 'I and v10)' The latter are each furnished with twoeut-out parts 10 and 1|, the first of these notches emerging on the upper edge of the plates while'the second emerges on the lower edge. The edges 12 and 13, respectively, of these notches are shaped so as to form a sloping surface of which the cut is bevel shaped, as may be seen at 12a and 13a, more especially in Figures 21 and 22, and these edges are designed so that the sharp end of the edge 12 lies above the upper table 2|, While the sharp end of the edge 13 is arranged below the lower table.

At the time ofthe forward movement of the package, the upper end tongues go into the opening 13, and under the action of the bevelled surface 12, they are folded back against the extreme ends of the package by pivoting round the edges ad' and bc' respectively. The folding is thenatthe stage illustrated by Figure 5.

Then the lower end tongues go in their turn into the opening 1| and, under the action of 'the bevelled surface 13, they pivot round the edges ad and be respectively; they are also folded back against the extreme ends against which they are held. by theactionv'of the plates 3| and 32, which ensures the pasting of the tongue pieces by the gummed part 3. The folding is completely nished (Figure 6) and the package continues being drawn by the slide 53 and is led to the rear end of thetable 20 from where it will be removed by any suitable means.

With the package released out of the mould,

the cam 5| causes the angular displacement of the lever 52 that returns the pinion 54 to its original position illustrated in Figure 8. The slide 58 then returns to the rear part of the mould and the shoe 6| is collapsed so as to leave free the upper surface of the table 20 (position illustrated in Figure 11).

The shoe 4| has resumed its inoperative position as soon as the package has stopped acting on the end of the control lever acting onthe lever 40.

A. new paper sheet is engaged and held stretched between the rollers IB and |9. A new package is then brought by the push-rod ID and the cycle as disclosed is repeated.

The paper sheets intended for the fashioning of the packages are delivered from a paper strip unwinding from a reel (Figures 7 and 9).

Itis well known that the reeled paper has aA greater strength in the longitudinal direction of the wound strip than in the lateral direction of this strip.

` The paper feeding device of the machine disclosedenables the sheet to be directed Aso that its longitudinal direction lies in the direction of the length of the package along which the sheet is subjected to the greatest strain.

With this object in View, the reel 80 is arrangedcrosswise in relation tothe machine ,as shown in Eigures 7 andV 9. The strip, drawnby the roller 8 |v. lon which'it is vpressed by the pressing roller 8|a,-A passes .overv two.` rollers -82v Aused i017 eliminatingV any buckling of the paperj ensuing from its windings, The diameter andV rotary speed of the roller 8| are xed so as todeliver the paper lengthirequired ,to Acover the. package in the die rection of its length, consideration`A being taken of--the lateral Vtongue pieces that are ,folded back on `the endsof -the;package.

On leaving the guillotine, the sheet is supported by a horizontal table provided with two rollers 84, 84a, also assuming an intermittent movement and driven for this purpose by control means connected with the transmission gear 86.

The rotation of the rollers 84, 84a brings the paper sheet between two rollers 90, 98a and these also assume an intermittent movement.

Then the sheet goes between the rollers 8| and Sla of a standard mechanism ensuring the gumming of the paper.

The roller 9| is subjected to the action of a cam that presses the gumming roller on the paper sheet at the places where the gum has to be applied.

Finally, the paper sheet comes between the rollers |8 and I8, as previously stated.

The reel 80 is carried by a horizontal spindle 82 (Figures 7 and 9) resting on a support 93 integral with the machine.
